}Expand description
Converts Thrift identifiers, primitives, containers or structs into a stream of bytes.
This trait does not deal with higher-level Thrift concepts like structs or
exceptions - only with primitives and message or container boundaries.
Write methods take an identifier (for example, TMessageIdentifier) or a
primitive. Any or all of the fields in an identifier may be omitted when
writing to the transport. Write methods may even be noops. All of this is
transparent to the caller; as long as a matching TInputProtocol
implementation is used, received messages will be decoded correctly.
All methods return a thrift::Result. If an Err is returned the protocol
instance and its underlying transport should be terminated.
§Examples
Create and use a TOutputProtocol
use thrift::protocol::{TBinaryOutputProtocol, TFieldIdentifier, TOutputProtocol, TType};
use thrift::transport::TTcpChannel;
let mut channel = TTcpChannel::new();
channel.open("127.0.0.1:9090").unwrap();
let mut protocol = TBinaryOutputProtocol::new(channel, true);
protocol.write_field_begin(&TFieldIdentifier::new("string_thing", TType::String, 1)).unwrap();
protocol.write_string("foo").unwrap();
protocol.write_field_end().unwrap();Required Methods§
